Yeah, Cullen. I'm trying to be constructive. Even if it's dumb luck, BRT just plain works consistently for routing. But I could pick on a bunch of other stuff, like no good way to organize or sort the routes. No way to share or post routes to social networks, no activity logging, no route editing, no color coding, etc that your site provides.
My latest trick that works pretty well was to write my own
VB script that takes your .tcx files and convert them to the .gpxx format that the bikehike.co.uk site provides. That makes the Garmin route between all the points on the .tcx vs just the turns/coursepoints on the GPX route. It also reduces the file size by 90%. Unfortunately, this method only works on certain units, such as the Edge 705.
Otherwise, I can always load the course and the route at the same time, and if they differ, just stop navigation on the 705 and rely on the course. Anyway, I do recommend that people check out your site. I know you folks have been at it a while and the functionality is really coming along!
